The average person takes thousands of steps each day, instinctively walking heel-to-toe. Although they hardly register them, those consistent heel-first strides are more unique to humans than previously thought and allowed early hominins to walk farther more efficiently, but at the cost of higher impact forces on bones and joints, according to a new study led by a researcher at Penn State.

Two months flat on their backs revealed the shocking speed at which the human body surrenders to gravity's absence—and what that means for astronauts, the elderly, and anyone immobilized by illness.

What mountaineers thought impossible, the human body quietly proved it could endure.

Spaceflight can do strange things to the human body — including making it harder for astronauts to poop.

Imagine trying to swallow a sip of water while your face feels stuffed with congestion, your sense of taste is dulled and your body is floating 250 miles (400 kilometers) above Earth. That scenario is part of everyday life for astronauts aboard the International Space Station. Spaceflight changes the human body in dramatic ways. Muscles […]

Scientists drew blood from climbers near Everest’s summit and found oxygen levels that should have been lethal.

F1 races are exhilarating. While racing alongside 21 other cars, an F1 driver can reach speeds of up to 231 mph, making it one of the world’s most dangerous sports. And F1 drivers need to be physically prepared to prevent disaster. Over the course of a single race, they experience hundreds of pounds of force, […]

Humans look, at first glance, like a poor design for saving water. We have unusually dense eccrine sweat glands, we can sweat heavily for long periods, and our cooling system depends on losing water through the skin. But a Duke-led study reached a less obvious conclusion: compared with other great apes, humans appear to process substantially less water each day. The body that became unusually goo…

If pressure in a vacuum is very low, water can evaporate even at low temperatures, since the lower the pressure, the lower the boiling point. So, if I were suddenly exposed to the vacuum of space, would my body freeze, or would it expand as the water in my body turned into gas?

An international team of researchers has completed one of the most comprehensive longitudinal molecular studies of human diversity ever conducted, uncovering how both ethnicity and geography shape human biology at The post Global Multiomics Study Reveals How Geography and Ethnicity Shape Human Biology appeared first on Institute for Systems Biology (ISB) .

Through a flipped classroom, weekly labs and a medical school visit, the anatomy and physiology sequence prepares students for the demands of healthcare. The post Anatomy and Physiology Sequence Gives Students Strong Foundation in Human Biology appeared first on Syracuse University Today .

A new nationwide study led by the University of Maryland is seeking volunteers to help document and analyze the full range of human flatulence. Researchers at the University of Maryland have unveiled what they describe as the first wearable device built specifically to measure human flatulence. Known as Smart Underwear, the discreet sensor system tracks [...]

After his daughter's diagnosis, Budimir Šobat gave up drinking and devoted himself to her care. Years later, he found a new obsession: holding his breath longer than anyone in history. The post The Man Who Held His Breath for 24 Minutes appeared first on Outside Online .

Ingrid Seagren competed in the Canal Run 5K, winning the women’s category and finishing 5th overall. She is going into her sophomore year pursuing a major in Human Biology with minors in pre-health and German. After she graduates, she plans to go to medical school and eventually become a physician. Plus, Ingrid is very active . . .

UC Irvine is a popular choice for undergraduates hoping to pursue careers in the medical field. As such, countless students have looked to the School of Biological Sciences to prepare […]

Kate Meister sees her best path to becoming a Physician’s Assistant through the Biology department. She is a senior studying Human Biology. One of the degree requirements is to complete a capstone. She chose to do an undergraduate teaching experience with Travis Wakeham. Kate is passionate about biology and education, so she and Travis are . . .

Did you know blood makes up around 7% of the weight of a human body? The average adult has 5 litres of blood flowing around their body in a massive network of arteries and veins transporting oxygen and nutrients to cells. Blood also removes waste, contains cells that fight infection and helps with temperature regulation. […] The post Science activities for learning about blood appeared first on S…
